A sleeveV b whose conici-ty corresponds with the conicity of the fuel reservoir a and which is closed at the upper end is mounted upon said fuel reservoir; it has threads designed to receive the screw cap g. The bottom of the screw cap has a circular opening so that it forms an inwardly projecting' ring-shaped bead g. Between thefbead g' and the end face of the sleeve- Z1 the 'mounting for the ceriurn is located which consists of a circular disk e lhaving a rectangular opening e. Two opposite edges of the opening e are bevelled downwardly so that a dove-tailed recess is formed in which the ceriumv piece f is inserted which has two bevelled side faces f.

Owing to the peculiar construction of the sleeve described, the cerium piece is countersunk and removable'.

The pocket lighter presents an absolutely smooth` outer surface4 and is consequently To all whom t may concern: v

Be it knownthat LFRrrz Buon, a citizen A have invented certainnew and useful Improvements in Cerium Pocket Lighters, for which I have filed application in `ermany, March 24, 1919:, Patent Number 342049, of which the following is a specification.

AThisv invention relates to a cerium pocketv lighter which differs `from the pocket lighters of the same type and of lmown construction in so far that the cerium is countersunk and removably mounted in the end face of the tubular cover, and that the friction de# vice has the shape of a large knife mounted by means of an annular shaft in the wick tubeseated upon the fuel reservoir.

In order that the invention may bel clearly understood, I shall proceed'to describe the shown by way of example in the accompanyin drawing, whereinvr i5 ig. 1 shows the pocket lighter in axial section. to be stored easily in a pocket.

Figs. 4 yand 5 show the tubular. cover in side elevation andinfplan view respectively.

Figs. 6 and 7 .are a side elevation anda plan view respectively of the mounting of' the cerium.

Figs.v 8 and 9 represent the cerium in side elevation and in plan view respectively.

Figs. l0 and 1l show thescrewcap'for fixing the mounting of the'cerium in side out. The cerium piece can be removed b a slight, pressure from its mounting andY a new piece of cerium can be inserted. The fixation is effected in an equally simple manner butin inverse successio Y Owing tov the' conical shape of the fuel 85 reservoir and of the sleeve a gas tight joint is eected between said two' parts so that no loss of fuel can occur. To make the pocket lighter ready for use it is merely necessary to remove the sleeve and to rubV the knife al along the opening e over the cerium f to producestrong sparks which light the wick. The wick holder c remains in the fuel reservoir so that no fuel can he lost even when'the pocket lighter is being use The comparatively Figs. 12, 13 and 14 vice in die'rent views. A

Figs..15 and 16 are respectively a sideelevation and a view fromV below of the wick holder.

The :fuel reservoir a consists of aconical tube closed at the lower fend by a bottom` plate and at the upper end bythe wick ln the wick holder-c 'the'hife d of peculiar shape is mounted-.whose cutsituated transversely to the axis of the wick holder or sli htl hifi' show the friction' delarge cutting edge d rubs lover the entire widthV of the cerium piece but does not penetrate into the same, Y so that no cerium is wasted. When the cutting edge has become blunt it can be easily"`` -.sharpelielforthe knife can be replaced by anew e. er shaft d which fits'v the The 'benzine f. reservoir forms Y a handy d has anannu handle, so that the knife is better guided in the slot of recess e than the thin friction member of the pocket lighters of known construction, with which it happens frequently that the knife slips 0E the cerium unless the lighter is handled carefully.

The improved construction of the pocket lighter, which could evidently be oval, flat edged or of other shape, offers the further advantage that the wick can be easily replaced.

I claim 1. A pocket lighter of the type described in which the ignition means is arranged in the enclosing cap which fits over the burner piece or tinder holder comprising in combination an enclosing cap, a striker of the shape of a knife with broad edged blade, an ignition metal piece of rectangular shape having two side faces bevelled from below upward, a ringvremovably inserted in said cap having a rectangular opening and two side faces inclined so that they fit on the inclined side faces of said ignition metal piece designed to securely hold said ignition metal piece and to serve as-guide for said striker.

2. In a pocket lighter of the type described striker, and a screw cap screwed upon said enclosing cap to hold the ring in position andhaving a rectangular opening in the top plate which is smaller t an said ring.
